Specification of Letters Patent. Patented Aug. 12, 1919.

Application filed June 12, 1917. Serial No. 174,310.

To all whom it may concern;

Be it known that I, EDWARD A. LINDSLEY, a citizen of the United States, residing at Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Apparatus for Coating or Impregnating Posts, of

. which the following is a specification.

My invention relates to improvements in apparatus for coating I or impregnating posts, or other wood products to whichit is desired to apply a liquid preservative intermediate of their ends or to any other portion of their length.

One ob'ect thereof is the provision of an efficient liquid preservative applying apparatus of novel construction, and an additional object resides in providing, in 'conjunction with said apparatus, a thoroughly efficient and practical means for effecting an economical handling of the product before during, and after treatment.

The invention consists broadly of an endless chain post conveyer, preservative sprayers disposed below the conveyer and adapted to direct the preservative fluid upwardly, preservative sprayers superposed above the conveyer and adapted to direct the preservative in a downward direction, a source of supply of the preservative, and a source of pressure for the preservative.

The invention includes other and minor features of construction all designed-to cooperate to insure the most advantageous op eration of the apparatus.

Referring to the accompanying drawings which illustrate one embodiment of the invention- Figure 1 is a side view in elevation of the complete treating machine as it appears in actual operation and showing a number of posts in the course of treatment and handling, and a partial view of a railway car to which the treated posts are intended for delivery.

Fig. 2 is a top plan view showing the apparatus in two fragments.

Fig. 3-is a fragmental, part sectional view in side elevation, illustrating the immediate post treating apparatus in operation.

Referring more specifically to the drawings, in which like characters of referenceare used to indicate like parts in the several views, the numeral 1 designates a preserva tive tank which is preferably supported upon-the frame structure floor 2 and disposed below and between the endless, inclined elevator chains 3 which are driven by sprockets 4 fixedly mounted on shafts 5 and 6, power to operate the chains being supplied from an engine 7 and transmitted to the shaft 6 through pulleys 8 and 9 and belting 10. The sprockets and chains are supported by the uprights 11, side members 12 and brackets 18 extending from the latter.

Leading from the preservative tank 1 is a preservative supply pipe 14 which termi nates in upper branch sprayer pipes 15 which carry at their ends longitudinal, superposed sprayer heads 16 adapted to direct the preservative fluid, such as creosote, downwardly at converging an les. A branch supply pipe 17 leads from t e supply pipe 14. and terminates in branch sprayer pipes 18 having at their ends longitudinal sprayer heads or atomizers 19 disposed somewhat below the upper reach of the elevator chains and adapted to direct the preservative fluid upwardly at converging angles. As clearly shown in Fig. 3 the opposed sprayer heads serve to direct the fluid to apply it effectually to all surf-aces of the treated objects supported upon the upper reach of the elevator chains 3, said objects being engaged and held by the projecting cleats 20.

In practice, the posts are first deposited from a vehicle upon the inclined skid arms 21 which slide the same down upon the elevator chains. After reaching the conveyor chains the ends of the posts are successively engaged by aguide plate 22 which shunts the posts into uniform positions on the chains for the spraying treatment. From the point of the spraying operation the posts pass onward to the upper end of the elevator Where they are received upon a skid 23 which is pivotally supported upon the sprocket shaft 6, being rendered pivotally adjustable by means of a pivoted arm 24 having one end slidably engaged in a slot 25 of the skid and adapted to be secured by a thumb screw 26. As illustrated in Fig.- 1, the skid 23 is intended to deposit the posts onto a railway car 27 Where they may then be conveniently handled for piling. When the car is to be removed the skid is dropped to allow the necessary clearance between the car and apparatus.

A drain pan or trough 28 is located just below the elevator and is adapted to catch the excess of preservative and the drippings from the treated objects and return the same through a pipe connection 29 back to the preservative tank 1. The superposed sprayer heads or atomizers are provided with a shield 30 to confine the spray from the lower atomizers and effect its return to the drain pan 28.

The supply tank 1 is divided by a central partition 31 into an upper reserve supply compartment 32 and a lower delivery compartment 33, the drippings and excess preservative above referred to being received in the reserve compartment after being clarified by a suitable screening (not shown) or before being piped into the delivery compartment through a connecting pipe 34:.

The steam boiler 35 and the engine 7 are intended to supply air pressure to the supply tank delivery compartment, or steam thereto from the boiler, in the latter case through a pipe 36 to introduce the required pressure and also to mingle steam with the preservative to heat the same.

Having described my invention, I claim 1. In an apparatus for coating posts, the combination with a conveyer, an open trough, and a drain pan forming part of the trough, of an upper sprayer to spray downwardly, and an opposed lower sprayer to spray upwardly, a transversely extending shield over the upper sprayer, and means for supplying a preservative fluid under pressure to both sprayers.

2. In an apparatus for coating posts the combination with a pair of spaced conveyer chains and an inclined trough located beneath the upper flights of the chains, and said trough having a drain pan at the lower end of the trough, a lower sprayer projecting upwardly through the pan, an opposed upper sprayer to spray downwardly toward the pan, a transversely extendin shield in connection with the upper sprayer for the lower sprayer, and means for supplying a preservative fluid under pressure to both sprayers.

In testimony whereof aiiix my signature EDWARD A. LINDSLEY.
